Scan your system for malware?

Latest flash installed? Run java? Unless you need java, I'd uninstall that, due to continuing security concerns. Yesterday, Secunia reported 11 new security vulnerabilities with the latest version available. Anything from Oracle should not be on a system for now.
i am recently having a weird lagging on my laptop,basically when i brows internet pages with videos in them or when i play games(during playing when loading from hdd the game freezes for seconds and audio lags).i tried almost every thing i could to determine what causing the problem,i updated my graphics card driver,uninstalled some new programs ,did a clean and a fix for registry with ccleaner.nothing solved the problem.i tried to monitor the system with task manager,but i could not see strange prepossess,and cpu and ram load are normal like before.is there a better way for monitoring performance and solve this problem?
